Parking meter



FIG. 1 is a front left perspective view of a parking meter showing our new design; and,

FIG. 2 is a rear perspective view thereof.

In the drawings, the broken line showing of a coin slot region, surface labeling and buttons, status indicator and rear window depict environmental subject matter and forms no part of the claim. 

We claim the ornamental design for a parking meter, as shown and described.
